Which one of the following connectivity matrices is correct to show the given network of six nodes?

Correct option is B

A connectivity matrix is a square matrix that represents the connections between nodes in a network. Each row and column correspond to a node, and the presence of a direct connection between two nodes is marked with 1, while the absence of a connection is marked with 0.

• Node 1 is connected to Node 2 and Node 3.
• Node 2 is connected to Node 1, Node 3, and Node 4.
• Node 3 is connected to Node 1, Node 2, Node 4, Node 5, and Node 6.
• Node 4 is connected to Node 2, Node 3, and Node 5.
• Node 5 is connected to Node 3 and Node 4.
• Node 6 is connected to Node 3.

This matrix shows the following direct connections between the nodes:

• Node 1 is connected to Node 2 and Node 3.
• Node 2 is connected to Node 1, Node 3, and Node 4.
• Node 3 is connected to Nodes 1, 2, 4, 5, and 6.
• Node 4 is connected to Nodes 2, 3, and 5.
• Node 5 is connected to Nodes 3 and 4.
• Node 6 is connected to Node 3.
